My smart, Sneaker, was backed into today by a friend as he was pulling out of a garage

The front right bumper piece is the only part that is damaged, and it has a pretty sizable hole in it. The plastic interior was originally bent in. but we popped that part back out. Drove it back on the highway to get it home, and it felt fine.
Does anyone have an idea how much it will cost to fix or have people had similar experiences?
